This medium contains hyaluronan which combines to have normal DNA. Selecting sperm contained hyaluronan are mature sperm and will good quality of embryos.
The ICSI procedure is performed by using a technique called micromanipulation. Micromanipulation uses a special microscope, along with very small surgical tools, to pick up and handle one single sperm, injecting it directly into an egg.
ICSI is generally used for patients where there is a male infertility factor or fertilisation problems.
